✦ Synopsis

Abstract

The ^13^C and ^77^Se NMR spectra of eight new unsubstituted biheterocycles containing a thiophene or selenophene ring condensed with an isothiazole or isoselenazole ring were recorded. The assignments of the ^13^C signals were made by the examination of chemical shifts, ^1^J(CH) coupling constants and, for the quaternary carbons, on the basis of ^1^J(C, ^77^Se) coupling constants. The results are compared and discussed.

## Abstract The ^77^Se, ^13^C and ^1^H NMR spectra of the products of phenylselenenyl azide and chloride addition to methylenecyclohexane and cyclohexene are presented. Scalar couplings between ^77^Se and ^1^H/^13^C allowed the absolute assignment of the regioisomers in the ^1^H and ^13^C spectra.

## Abstract ^77^Se and ^13^C chemical shift of 19 1,2,3‐selenadiazoles are discussed in terms of substituent effects and conforma‐tional behaviour of the molecules. It is shown that the ^77^Se chemical shifts of such compounds are suitable tools for chiral discrimination in diastereomeric compounds

C and 77Se NMR was carried out on dicyclopentadienyl derivatives of Ti, Zr and W with selenium bonded directly to the metal. Although '"C NMR is not sensitive to different substitution, 77Se NMR is valuable and refiects the influence of the different organic substituents and the nature of the metals
